If your answer is not B an integer, round your answer to one decimal place. (b) What is the mean of this data set? If your answer is not an I] integer, round your answer to one decimal place. (c) How many modes does the data set have, and what are 0 zero modes their values? Indicate the number of modes by clicking in the one mode- appropriate circle, and then indicate the value(s) of the O ' l] mode(s), if applicable. 0 two modes: I] and I] 3- A private college advertised that last year their freshman students, on average, had a score of 1160 on the college entrance exam. Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true.
